This invention relates to tubs of that type generally known as slack tubsf used for chilling metals during they tempering process.

VIt. is an object of the present-invention to vprovide a device of this"character 'designed primarilyk for `use in tempering the sharpened ,cutting edges ofsteel bits, means being einployetlwliereby bits can be properly supported in the tub during -the `tempering lo operatioinythe position lof the edge of vthe bitzbeingvsuch that steadyflowof coolwater can be directed against said edge. Y

Altur'ther object is yto provide'k a tub of this character which can be quickly drained to prevent freezing of watertherein whenthe tubV is not in use. Y

A further obj ect is to provide a the interior parts removable so that the tub can be cleaned'readily and the parts re-placed by the ordinary mechanic.

With the foregoing and other. objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understoodthatchanges in the precise embodiment of the invention hereinL disclosed may be made within the scope of what is claimed, without departing from the spirit'of the invention.

In the accompanying drawings, the `preferred form of the invention has been shown.

In said drawings,

Figure 1 is a top plan view of the tub..

Figure 2 is a central vertical longitudinal section therethrough, the water pipe being shown partly in elevation. v

Figure 3 is ase'ction on line 3-3, Figure 2.-

Referring to the figures by charactersv of reference l designates a heavy "sheet metal trough having a rounded bottom, the upper edges of this trough beingturned outwardly and downwardly to provide reinforcing and protecting flanges 2. The ends of this trough arewelded or otherwise connected to Y heads 3 likewise formed of heavy sheet metal having outturned base flanges 4 for engaging a supporting surface One of these heads has a drain opening 5 near the top thereof and both of the heads are provided, on their inner faces,`with supporting brackets held to the heads by welding or in any other suitable manner, each bracket being formed with lspaced recesses T. Both brackets are designed to engage and support the ends of supporting rods 8 which bear firmly against tub having 'the heads andcan be'formed olihieavy f ritintermedi'ate'points the rods 8 bear upon` and are braced by a plate 9 in the torinof a webewhich is welded Vorf otherwise attached to the' vbottom portionofthe trough and 'a1 space 10 extendinginto the bottom edge Athereof so that'this web canthus bridge ythe water supply pipe 11 .extending longitudinally within the trough. VThis pipe 11 is mounted in one end only ot the `tulo and is provided', along its :uppermostportion', with f u alongitudinal series'of apertures 12 through which jets-ot watercan flow into the tub.,A single outlet' opening 13 can be providedin the bottom ol' the pi 9e 11 near one end. this opening being used lfor draining purposes.

It is to be understood that the pipe 11 is to be connected by a pipe to a source of water supply and water flowinginto the pipe 11 will escape through the openings 12 and fill the troughup to the level ofthe overflow aperture 5. v

The tub herein described is designed primarily for use in tempering the cutting edgesof bits used in drilling wells. After a bit has been'` sharpened andv heated it is lowered into the tub so as to reston the rods 8. Theheads of the bit will be presented toward the pipe 11 and `will bel quickly chilled b l the jets of fresh water flowing into the tub rom the openings12.

As shown particularly in Figure 1 the pipe 11 can be readily disconnected from the tub inasmuch as ythis pipe issupported in one ofthe end plates or heads 3 and held thereto by nuts .14 arrangedl to grip said head'or plate. Thus the pipe lcan be withdrawnfrom kthe tub and the rods 8, when not in use, can be driven upwardly out of position in the tub, thereby exposing the i interior` of the tub so Athat it can be cleaned readily. 1

In cold weather, while the tub is not in use, the Water can be drained therefrom by providing a three-way valve 15 at the outer end'of the pipe 11. By turningv this valve in one direction it can open into a vent 16 Yso that the contents of the tub and of the pipe 11 can thus drain through the vent. What is claimed is z, f l. A tub of the class described including a trough, end plates or heads connected thereto, a water supply pipe extending lon-' gitudinally within` the bottom portion of the tub and having apertures for directing jets of water upwardly into the tub, vsupporting rods extending longitudinally within the tub above the supply pipe.

2. A tub of the class described including a trough end platesk or heads connected thereto, a water supply pipe extending lon-Y git-udinally within the bottom portion of the s y tub and having apertures for directing jets Va trough, end plates `or heads connected thereto, a water supply pipe extending longitudinally within the bottom portion of the tub and having apertures for directing jets of water upwardly into the tub, supporting rods extending longitudinally within the tub above the supply pipe, and means carried by the bottom portion of the trough for supporting said rods at intermediate points,

ture.

said rods being detachably'mounted on the supporting means and the heads ofY the tub.

4. A tub of the class described including a trough, heads connected to the ends thereof and constituting supports, one of said heads having an overflow opening, a water supply V'pipe detachably connected to one of the heads and extending;longitudinally within the tub, said pipe having outlet openings in the (upper, portionjtheieof or' directing ets of water upwardly within, they tub, there being a drain opening inthe lbottom of the pipe, brackets integral with the inner facesv of the heads, a supporting member carried `by vthe bottom of the tub and bridging the pipe,k and spaced supporting rods mounted on said memberl and uponthe brackets, said rods ybeing removable.`
